2 WEEKS AND STILL NO DELIVERY OF ORDER

I placed an order online 19.11 and was advised on check out 4-7 days for delivery. Each time i go look on the website to track my order the tracking is not updated and in fact is extremely incorrect - why there is even online tracking is beyond me if you cant have it right rather done have it. 2 of my items were handed to courier 21 November and I STILL DONT HAVE THEM. When emailing i get NO response so again something that doesn't work. When calling i get told the parcel is with the courier so how long does a courier company take to deliver? It is now 2 weeks and still no delivery or feedback from TFG Online?
